s CYLINDER Forv WASHING-MACHINES.

Specification of Letters Patent.

Application filed March 6, 1908. Serial No. 419,549.

Patented Sept. 29, 1908.

To all whom 'it may concern:

Be it known that I, CHnis'iiAN JENsEN,ie siding at Palmyra, in the county of Burlington and State of New Jersey, have'invented certain new and useful Improvements in Cylinders for lVashingMachines, of which the following is a specification. My invention relates to certain Vnew an useful improvements in cylinders for washing machinesandthe like and it primarily has for its obj ect to provide certain improvements on the type of washing machine cylinder disclosed in my copending application liled August 30, 1907, Serial No. 390,756.

In its genericV nature my present invention consists in providing a cylinder having a' pair of heads and an intermediate partition,

joined by a series of peripherally arranged ribs or bars spaced apartto permit passage of the wateritherebetween, said bars carry ing a series of staves having both edges beveled into a dove-tailed form in cross section and intermediate bars of corresponding form to coperate with thestaves to form water scoops. Y

Other details of construction which@ will be `hereinafter fully described,.also form a part of my invention.

.In the drawings,-Figure l, is aperspective view of a cylinder embodying my invention. 2-2 of F ig. l, showing the construction of the ribs and scoops onan enlarged scale.

Referring now to the accompanying drawings in which like letters and numeralsof reference indicate like parts in all of the figures 1 represents the cylinder which is composed of the end heads la--l2L and the intermediate partition 2.` The partition 2 isconnected with the end heads 1a by the cross bars or ribs 3 arranged equi-distant from the center 1 of the cylinder and to which the staves 4L and the intermediate bars 5 are secured. The staves 4- and bars 5 have their outer surfaces arranged in the arc of a circle having as its centerthe endsl of the cylinder and each stave 4 in my present invention consists of a bar of substantially dove tailshape in cross section to provide the beveled portions ia-/lb on the side edges of the stave, the outer'surface @being of greater length in cross section than the inner surface 4d which is adjacent to the bars or ribs 3.

Alternate r-ibs 3a maybe made of greater width than the remainingribs 3, if desired, and to these alternate ribs 3a the intermedi Fig. 2, is a cross section on the line ate bars 5 are secured, the bars 5 being of corresponding shape in cross section to the scoop bars i and arranged with their face 51 of least area at the periphery of the cylinder, i while their face 5c of greatest area lies adjacent to the rib 3a.

\ The barst and 5 alternating serve to provide water passages 6 and 7 extending in different directions into the cylinder so that as the cylinder is rotated in the direction of l the arrow in Fig. 2,\water will be scooped up into the cylinder through the passages 6 and ejected through the passages 7, and when rotated in the opposite direction to the arrow shown in Fig. 2, water will be taken into the passages 7 and ejected through the passages 6, thus allowing the cylinder to be operated in either direction as may be found desirable and rendering the operation of washing and rinsing` the clothes, which are introduced into thecylinder, very effective.

` .i The staves 4 and ribs 3 together with the bars 5 and ribs 3a, serve to clamp the screen sections 8 between them to form screen closures for the passages 6 and 7 to prevent the clothes passing therethrough and at the same time permit .the water to pass through the SCIGGIIS.

tion, the cylinder is revolved first -in one direction, and then in the other, causing the water to become agitated, due to the circulationthrougli the cylinder and passages 6 and 7, it being understood that the cylinder disclosed in the accompanying drawings, is rotatably mounted in the usual water tank., (not shown).

` yOn small washing machines a single compartment cylinder may be desired, and in that event the central partition 2 would be omitted.

By providing the bars 5 of similar form in cross section to that of the staves 4, but mounted on the ribs reversely to the staves, thepassages 6 and 7 will be provided the walls 4 and 5fl of which will lie parallel to one another, while alternate passages 6 and 7 will be directed in opposite directions with respect to the cylinder. It should also be observed that the screen sections 8 lie in the same cylindrical circumference while the outer surfaces te and 5 of the sta-ves 4L and bars 5 lie in one and the same cylindrical circumference, thereby eliminating any projecting edges beyond the plane of rotation of the surfaces t and 5 and thus obviating the danger of damaging the cylinder should obstructions be encountered during the rotation of the cylinder.

From the foregoing description taken in connection with the accompanying drawings it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.

l/Vhat I claim is:

l. A washing machine consisting of. ay pair of heads, a series of ribs connecting said heads and spaced apart, a series of staves connected to said ribs, and likewise spaced apart, said staves being dove-tailed in cross section, intermediate bars of substantially like form in cross section to the staves, interposed between said staves and spaced therefrom to form water passages between the bars and staves, said staves having` their surface of greatest area at the outside of the cylinder, and said bars having their surface of greatest area on the inside of the cylinder, substantially as shown and described.

2. A washing machine consisting of a pair of heads, a series of ribs connecting said heads and spaced apart, a series of staves connected to said ribs, said staves being dove-tailed in cross section, intermediate bars of substantially like form in cross section to the staves, interposed between said staves and spaced therefrom to form water passages between the bars and staves, said staves having their surface of greatest area at the outside of the cylinder, and said bars having their surface of greatest area on the inside of the cylinder, and wire screens secured between said bars and staves to form screen closures for the water passages.

3. A washing machine cylinder comprising end heads, a series of staves mounted between said heads and parallel with the axis of the cylinder, said staves being spaced apart, and of substantially dove-tailed form in cross section and intermediate bars of like form to the staves mounted between said cylinder heads but parallel with said staves,

said bars being spaced from adjacent staves to leave water passages therebetween and wire screens mounted in said water passages.

t. A washing machine cylinder comprising end heads, a series of staves mounted between said heads and parallel with the axis of the cylinder, said staves being spaced apart, and of substantially dove-tailed foi-n1 in cross section and intermediate bars ot .like form to the staves mounted between said cylinder heads but parallel with said staves, said bars being spaced from adjacent staves to leave water passages therebetween, wire screens mounted in said water passages, said bars being arranged with their surface of least area at the outside of the cylinder to form in connection with adjacent staves water passages, that on one side of each bar being directed in a direction opposite to that on the other side of the respective bar, substantially as shown and described.

5. In a washing machine cylinder, the end heads and the connecting ribs therebetween, said ribs being spaced apart combined with staves secured to alternate ribs and provided with bevels on each of their longitudinal edges diverging from the ribs, bars secured to alternate ribs and provided with bevels on each of their longitudinal edges converging from the ribs to form in connection with the staves water passages between adjacent bars and staves, said water passages alternating in direction and a wire screen held between the ribs and the staves and the bars.

G. In a i Yashing machine cylinder, the end heads and the connecting ribs therebetnuan, said ribs being spaced apart, combined with staves secured to alternate ribs and provided with bevels on each of their longitiulinal edges diverging from the ribs, bars secured to alternate ribs and provided with bevels on each of their longitudinal edges converging from the ribs to form in connection with the staves water passages between :uljacent bars and staves, said water passages alternating in direction, and wire screens held in said vatei' passages.
